The dispatching method of the real-time process can be applied in above-mentioned terminal shown in FIG. 1.In Fig. 5, the dispatching party of the real-time process
Method includes:
Step 511, the first central processor CPU is selected from terminal according to predetermined selection mode.
In the embodiment of the present application, the implementation procedure of step 511 and the implementation procedure of step 210 are identical, no longer superfluous herein
It states.
Step 512, whether the first CPU of detection is in closing scheduling method.
In the embodiment of the present application, the implementation procedure of step 512 and the implementation procedure of step 220 are identical, no longer superfluous herein
It states.
Step 520, when the first CPU, which is in, closes scheduling method, whether the 2nd CPU of detection, which is handling hard break, is appointed
Business.
In the embodiment of the present application, the implementation procedure of step 520 and the implementation procedure of step 320 are identical, no longer superfluous herein
It states.
Step 530, when the 2nd CPU is not handling hard break task, whether the 2nd CPU of detection is related to handling traps
Task.
In the embodiment of the present application, detect whether the 2nd CPU is related to handling the implementation procedure of traps task in step 530
Identical with the implementation procedure of step 420, details are not described herein again.
It should be noted that the execution sequence of step 520 and step 530 can be interchanged.For example, terminal first detects second
Whether CPU is related to handling traps task, and then, when the 2nd CPU is not related to handling traps times, whether the 2nd CPU of detection
Handling hard break task.
Step 540, when the 2nd CPU is not related to handling traps task, determine that the 2nd CPU is not at closing scheduling mould
Formula.
Step 551a is detected in the 2nd CPU when the 2nd CPU, which is not at, closes scheduling method with the presence or absence of than target reality
The high process of the priority of Shi Jincheng.
In the embodiment of the present application, when the 2nd CPU, which is not at, closes scheduling method, terminal can also detect the 2nd CPU
In whether there is the process higher than the priority of target real-time process.
In one possible implementation, terminal indicates the priority of process by numerical value.For example, terminal can make
With the real number or integer value expression priority in [0,99] section.Such as the numerical value of the priority of process A is 67, process B's
The numerical value of priority is 89, and the numerical value of the priority of process C is 36.Then the priority of process B is higher than the priority of process A, into
The priority of journey A is higher than the priority of process C.
Step 551b, it is when the process higher than the priority of target real-time process is not present in the 2nd CPU, target is real-time
Process is placed in the 2nd CPU and handles.
Step 552a obtains the surplus capacity of the 2nd CPU when the 2nd CPU, which is not at, closes scheduling method.
In the embodiment of the present application, when the 2nd CPU, which is not at, closes scheduling method, terminal obtains the residue of the 2nd CPU
Ability.In one possible implementation, terminal can obtain the surplus capacity of the 2nd CPU, which can refer to
The residual time length for being presently in the process of reason, such as 2 milliseconds, 5 milliseconds etc. are completed in one CPU operation.
Step 552b, it is when the surplus capacity of the 2nd CPU is not less than the requirement capability of target real-time process, target is real-time
Process is placed in the 2nd CPU and handles.
It in the embodiment of the present application, will when the surplus capacity of the 2nd CPU is not less than the requirement capability of target real-time process
Target real-time process is placed in the 2nd CPU and handles.It should be noted that working as the demand energy of surplus capacity and target real-time process
When power is indicated with duration, the residual time length that the process for being presently in reason is completed in the 2nd CPU operation is shorter than target real-time process
When institute's received waiting time threshold value of energy, indicate that the surplus capacity of the 2nd CPU is not less than the requirement capability of target real-time process.
For example, institute's received waiting time threshold value of energy of target real-time process is 50 microseconds, the 2nd CPU operation is completed current
The residual time length of handled process is 30 microseconds, then illustrates that the surplus capacity of the 2nd CPU is not less than the need of target real-time process
Ability is sought, target real-time process is placed in the 2nd CPU handles at this time by terminal.
In one possible implementation, the surplus capacity of CPU is that the total capacity of CPU subtracts operation process on CPU
The sum of load.
As the substitution implementation of step 552b a kind of, terminal can also traverse CPU all in terminal, obtain wherein
Surplus capacity is strongest.In a kind of realization scene, terminal can also traverse CPU all in terminal, obtain wherein residue etc.
It is shortest to duration, target real-time process is placed in residue waiting time shortest CPU and is handled.
Optionally, target real-time process is being placed in the 2nd CPU before processing, terminal can also judge the 2nd CPU
In process whether positive carry atomic lock etc. forbids the lock of process preemption mechanism, above-mentioned process preemption mechanism of forbidding if it does not exist
Lock, then target real-time process is placed in the 2nd CPU and handles by terminal.
In conclusion the present embodiment can not handle hard break task in the 2nd CPU, it is not related to handling traps, and
The priority ratio target real-time process of process therein is low, and the surplus capacity of the 2nd CPU can satisfy the demand energy of the 2nd CPU
When power, target real-time process is placed in the 2nd CPU and is handled, enables the terminal to determine that influencing target real-time process executes speed
Each factor of degree avoids blindness of the target real-time process before execution and waits, reduces the operation of terminal processes real-time process
Delay, improve the efficiency of terminal operating real-time process.
Referring to FIG. 6, it illustrates the knots of the dispatching device of the real-time process of one exemplary embodiment of the application offer
Structure block diagram.The dispatching device of the real-time process can pass through the whole of software, hardware or both being implemented in combination with as terminal
